Potential
Define Potential Energy
What is stored energy?
What is kinetic energy?
energy in motion
What is thermal energy?
heat is thermal energy it can be transferred from one place by one place to another
What is the energy transformation of a burning candle?
Chemical->Thermal + Light
Define Conduction
Heat transferred by direct contact
In a roller coaster, where does the cart have the most potential energy?
At the top of the first hill or at the highest point
What is an example of kinetic energy?
a car rolling down a hill
What is the difference between potential and kinetic?
Potential energy is energy waiting to go into motion. Kinetic energy is energy in motion.
Daily Double!!!
What is the energy transformation in the Human body?
Chemical->Heat
Define convection and give an example
Convection is heat transfer through fluids by currents. Ex. water boiling, heating a room
What does potential energy depend upon?
Mass and Height
What happens to the amount of kinetic energy when two objects collide?
The kinetic energy from the objects gets transferred to one another
which law states that energy cannot be created or destroyed?
Law of Conservation of Energy
What is the energy transformation in a flashlight?
Chemical->Electrical->Heat and Light
Define Heat transfer by Radiation
Heat transfer through waves via a vacuum or empty space
Which will have more potential energy and why:
-A car at the top of the hill OR
-A rock at the top of the hill.
A car at the top of the hill because the car has more mass than the rock.
Kinetic energy decreases as ........decreases?
mass or velocity
Daily Double!!
Why can energy only flow from hot to cold and not the other way around?
Because hotter objects have more kinetic energy and therefore their particles are moving faster.
What is the energy transformation in a campfire?
Chemical->Heat and Light
Give an example of Conduction
(Anything that sounds correct)
What is how dose a pendulum represent potential energy?
when it goes up it has potential energy
Daily Double!!
How does a pendulum represent potential to kinetic energy?
Because when it is at its highest point then it is potential energy and when it rolls down to its lowest point it is kinetic energy.
What is how does energy flow when you have ice water and hot chocolate?
hot to cold
What is the energy transformation in a windmill?
Kinetic->Electrical and Mechanical
What is one thing that shows conduction, convection and radiation?
A fire because when you put your hand over it you get convection, when you hang marshmallows over it you get conduction and when you put your hand beside it you get convection
